Book ChapterDOI
Parameterized approximation via fidelity preserving transformations
TL;DR: A new parameterized approximation paradigm which studies the interaction between performance ratio and running time for any parametrization of a given optimization problem is motivated and described, and the concept of α-shrinking transformation is introduced, for α≥1.
Journal ArticleDOI
Dynamic Dominating Set and Turbo-Charging Greedy Heuristics
TL;DR: In this paper, a dynamic version of the DOMINATING SET problem is introduced and proved to be fixed-parameter tractable (FPT) in settings where problem instances evolve, and the main purpose of this paper is to exposit two very different but very general, motivational schemes in the art of parameterization.
Journal ArticleDOI
Myhill---Nerode Methods for Hypergraphs
TL;DR: An analog of the Myhill–Nerode theorem from formal language theory for hypergraphs is given and a method to derive linear-time algorithms and to obtain indicators for intractability for hyper graph problems parameterized by incidence treewidth is obtained.
Journal Article
A Note on the Computability of Graph Minor Obstruction Sets for Monadic Second Order Ideals.
TL;DR: It is shown that the obstruction set for an ideal in the minor order cannot be computed from a description of the ideal in monadic second-order logic.

What is known about Vertex Cover Kernelization
TL;DR: A survey on kernelization of the vertex cover problem can be found in this article, where the authors dedicate this survey to Professor Juraj Hromkovic on the occasion of his 60th birthday.
